FOX-STRAPPING DEVICE.

Application filed December 16, 1920. Serial No. 431,072.

To all whom it may concern: Be it known that I, SIDNEY \V. TREAT, acitizen of the United States, and a residentof Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Box-Strapping Devices, of which the following is aspecification.

This invention relates generally to improvements in box strappingdevices, and

4 more particularly to an edge protector or box corner plate, adaptedfor use with metallic banding material such as is applied as a binderfor the ordinary forms of boxes and packages used for shipping purposes.These banding materials may be in the form of flat metal strap or wire.

An edge protector'of the character herein described is useful to protectthe corners of a fibre carton or box against being crushed by thebinder; also to protect the binder against being caught on nails or thelike.

A preferred form of edge protector embodying the features and qualitiesindicated will now be described in detail, and in connection with theaccompanying drawings, in which- Fig. 1 is a perspective view of a boxto which flat metallicbox strapping is applied to ether with the edgeprotector,

Tig. 2 is an enlarged perspective viewof a single corner piece showing.the structure thereof, and I Fig. 3 is a detailed view in section takenon line 3-3 of Fig. 1.

As clearly shown in Fig. l, the box 1 is bound by metallic straps 2-2passing completely around the same. The straps may be connected undertension at their ends by means of any suitable joint.

Referring first to the structure of a single edge protector, the same isstamped from a blank of sheet metal in a form comprising in general twowebs ';l 4 arranged at right angles to each other, these web's meetingin a tubular bead 5 extending along the meeting edges of the webs, andarranged symmetrically with respect to the planes of said webs. Asclearly shown in Fig. 3, the bead projects beyond the outer surfaces ofboth webs, its conformation being more accurately identified as an aredescribed about the line of intersection of the extended planes of saidwebs. As a preferable construction, l'lf/WV- ever, the ends of the bead5 are flattened as at 6-6 for the manifest purpose of eliminat ing theabrupt and sharpened ends, as Will hereinafter be pointed out.Intermediate of, and preferably midway between the ends of the device,and formed on opposite sides of the bead are longitudinally extendingslots 77 corresponding in length and width to the dimensions of thestrapping. Each slot is positioned slightly above the surface of theadjacent web, and in alignment with the path of a binder in passingaround the box corners, and in contact with; the webs of the device. Ineach of the webs are formed prongs 8 arranged in any suitable manner,although preferably located on either side of the path of the strapping.The prongs are formed-by striking pointed projections from the webs,these projections or prongs being bent inwardly with the points directedtoward the intersection of the webs, and at an acute angle to thesurfaces of said webs.

The manner of applying the edge protector may be varied somewhat,although the ultimate result is the same; namely, the fastening of aplate along the edges of the box at the point where the strappings 2 -2pass around the same, said straps passing over one web through the slots7+7 and over the other web. Clearly the device could be applied at theproper points by striln'ng the same with a hammer, thereby driving theprongs into the walls of the box, and then passing the straps throughthe slots prior to the tightening and sealing of the latter, or the edgeprotector could be strung upon the straps and adjusted in properpositions in the operation of applying the straps, where upon the edgeprotector would then be driven home and the straps tightened and sealedas before.

The edge protector serves as an additional box strengthening member,reinforcing'the edges of'the box as well as providing protectivesurfaces to resist the tension exerted by the straps, and tending tobreak the edges of the box.

(,learly the use of the edge protector is not limited to any particulartype or shape of container, nor to any particular method of applying themetallic strapping, and for that reason I- do not Wish to be limitedexcept in so far as the specific structure, is set forth in the appendedclaims.

I claim as my invention p 1. A box reinforcing member including integralmetal flanges having the ma or portions thereof extending atsubstantially right angles to each other, said flanges being providedadjacent to their meeting edges with opposed openings adapted to receivea tensional binder.

2. A box reinforcing member formed of a metal plate having integralflanges, the major portions of which extend at substantially rightangles to each other, said flanges being provided with opposed openingsin their adjacent portions to receive a tensional binder 3. A box cornerreinforcement comprising in combination a air of flanges adapted tooverlie a box corner, points struck out from said flanges to anchor thesame on a box, a bead connecting the two flanges, said bead being cutaway to permit a metallic box binder to pass around the box cornerwithout going over the bead. e

1. A box reinforcing member including integral metal flanges, the majorportions of which extend at substantially right angles to each other,and means carried by said flanges for anchoring said member to a box.said flanges being provided with opposed openings adjacent to the linewhere said flanges are joined together to receive a tensional binder.

5. A box edge protector comprising webs arranged at an angle to eachother and meeting in a bead. and slots formed in transverse alignmentthrough said head.

6. A box edge protector adapted to be secured to'the surface of a box,and comprising a web, a projecting bead formed in the surface of saidweb, and a slot formed in said bead and adapted to admit. a box strap.

7. A box edge rotector adapted to be secured to the sul ace of a box.comprising a web, a bead formed in said web and projecting beyond thesurface thereof, there being slots in said bead forming a transversepassage therethrough adapted to receive a box binder.

8. The combination with a metallic box strap. of an edge protector,comprising webs arranged at an angle to each other. and a longitudinalbead atthe junction of said webs, there being slots formed on oppositesides of said bead through which said strap extends.

9. The combination with a metallic box binder, of an edge protectorcomprising webs, a tubular bead intermediate said webs, andtranseversely arranged openings in the wall of said bead through whichsaid binder -is adapted to extend.

10. The combination with ametallic binder, of an edge protectorcomprising a web adapted to engage flatwise the surfaces of a box, abead extending transversely of said strap and apertures formed in saidbead and adapted to receive said binder.

11. In a device of the character described, the combination of ametallic strap adapted to surround a box or the like, and an edgeprotector comprising webs bent at an angle to each other, a bead formedat the junction of said webs, and slots formed in opposite sides of saidbead adjacent the surface of said webs.

12. In a device of the character described, the combination of a strapadapted to surround a box or the like, and an edge protector comprisingwebs arranged at right angles to each other, and a tubular bead formedat the junction of said webs, saidbead being provided intermediateitsends with slots through which the strap extends. 13. In a device ofthe character described, the combination of a binder adapted to surrounda box or the like, and an edge protector comprising webs, and a tubularbead at the junction of said webs} the ends of said head beingflattened, and slots in the wall of said bead intermediate saidflattened ends, and providing a transverse passagefor said binder.

1 1. In a device of the character described, the combination of ametallic strap adapted to surround a box or the like, and an edgeprotector comprising webs arranged at right angles to each other, and abead at the junction of said webs, the ends of said bead beingflattened, and slots formed in opposite sides thereof and intermediatesaid flattened ends.

In witness whereof, I hereunto subscribe my name this 16th day ofNovember, A. D.,

SIDNEY W. TREAT.
